Sea levels across the Northeast coast of the United States rose nearly 3.9 inches between 2009 and 2010, according to a new study from researchers at the University of Arizona and the National Oceanic and Atmospheric Administration. The waters near Portland, Maine, saw an even greater rise — 5 inches — over the two-year period.

While scientists have been observing higher sea levels across the globe in recent decades, the study found a much more extreme rise than previous averages. Such an event is “unprecedented” in the history of the tide gauge record, according to the researchers, and represents a 1-in-850 year event.

“Unlike storm surge, this event caused persistent and widespread coastal flooding even without apparent weather processes,” the study’s authors wrote. “In terms of beach erosion, the impact of the 2009-2010 [sea level rise] event is almost as significant as some hurricane events.”
